After using Firefox for a while with a number of tabs open, sometimes links will
open in new (separate) windows rather than in the frame where they belong. These
new windows will lack a close button and Firefox crashes if you try to forcibly
close them.

The "main" or "real" Firefox window is left unusable where the frame should have
been. The space is not drawn, and does not react to mouse clicks. Reloading the
page or reopening the link (if it's in a frame) can sometimes cause the bogus
window to disappear and the page to be drawn in its proper place.

This happens both when opening links inside a tab, reloading a page in a tab,
opening a link in a new tab and opening a link which opens inside a different
frame on the same page. It seems to happen more the longer you've had Firefox
open, and possibly the more tabs you've been using, though that could just be a
"how much you've used it" criteria, but can sometimes pop up even after
relatively short periods of usage. It's not in any way reliable enough to
reproduce in any way I've managed to figure out.

A restart (of Firefox) "solves" the problem.

I've never experienced this running on Windows, but I'm unsure if it's ever
happened on Solaris. I'm running WindowMaker 0.80.2 on x.org 6.7.0 and Linux
2.4.26, but both different x.org/XFree86 versions and linux kernel versions seem
to be affected.

Also, this has been around since at least Firefox 0.9.
